Future Needs 



It has already been pointed out that there is a 

 growing tendency to purchase food materials on 

 the basis of composition. New discoveries in the 

 domains of plant composition and animal nutrition 

 and the improved methods of rapid and accurate 

 valuation will accelerate this tendency. Even now, 

 manufacturers of food products print on cartons 

 and in advertising matter quality reasons for the 

 superior food values of certain articles. At least 

 one firm produces two parallel sets of its manufac- 

 tured foods, one for the man who does hard physical 

 labor, and the other for the brain worker. Quality, 

 as related to the needs of the body, whether of beast 

 or man, is rapidly becoming the first question in 

 judging any food material. The present era of high 

 prices makes this matter even more important. 



In view of this condition and tendency, the fact 

 that dry-farm products are unusually rich in the 

 most valuable nutritive materials is of tremendous 

 importance to the development of dry-farming. The 

 small average yields of dry-farm crops do not look so 

 small when it is known that they command higher 

 prices per pound in competition with the larger 

 crops of more humid climates. More elaborate 

 investigations should be undertaken to determine
